Modular plumbing system

ABSTRACT

The present disclosure describes prefabricated, modular plumbing assemblies and methods of installing the plumbing assemblies. The plumbing assemblies contain all the components needed for a complete installation. The plumbing assemblies are modular and prefabricated, so that in most cases only one measurement is required on site for installation of the assemblies. The installed plumbing assemblies are at an appropriate finished height and orientation for connection to a plumbing fixture. The use of the plumbing assemblies of the present disclosure greatly simplifies the installation process, decreasing the labor cost associated with installation, decreasing the time needed for installation, saving on material costs and material waste and reducing the installation errors inherent in the current methods for installing plumbing assemblies.

FIELD OF INVENTION

[0001] The present disclosure relates generally to plumbing assemblies for connecting plumbing fixtures to the main plumbing system of a building, and specifically, to prefabricated, modular plumbing assemblies for such use.

BACKGROUND

[0002] Over the past several decades, the components comprising plumbing assemblies and the methods of installing the assemblies have become standardized. In terms of the methods of installation, the steps in the process depend in part on the structure of the building itself. Buildings are generally constructed with either of two types of foundations, concrete slab foundations or off-grade floor systems. When a concrete slab foundation is used, it is necessary to install the pipes comprising the main plumbing system of a building (the main water supply pipes and main drain pipes) and certain components of the plumbing assemblies before the concrete slab is placed. Therefore, these components must be placed in the correct orientation so the completed plumbing assemblies will be contained within the finished wall of the building so that the plumbing assemblies will not interfere with further construction of the building. Once the main water supply and drain pipes and the initial components of the plumbing assembly have been installed and pressure tested, the concrete slab is placed and construction of the building can continue. Once the building frame is constructed, typically using wooden frame members, the remainder of the plumbing assembly can then be completed and the finished walls of the building can be installed. This two step construction process is required because the complete plumbing assembly cannot be installed without the support provided by the building frame. Installation of the plumbing assemblies in off-grade floor systems can occur in one step, since the installation occurs after the building frame has been constructed.

[0003] The components used in the plumbing assemblies, although standard, require a skilled craftsman to install. For example, the components needed for a typical bathroom lavatory installation consists of two water supply pipes (one hot and one cold) connected to the main hot and cold water supply lines, a drain pipe connected to the main drain pipe, two air chambers connected to the water supply pipes and two fixture extensions that extend from the water supply pipes through the finished walls to supply water to the lavatory. In almost all cases, it is necessary to cut each of these components to the proper size and join these components together on site to produce the finished plumbing assembly. The connection of one air chamber to one water supply pipe requires that the supply pipe be cut to the proper height, a tee joint sweated onto the supply pipe to receive the air chamber, and the air chamber sweated onto the tee joint. This process must be repeated for the second water supply pipe and air chamber. In addition, the rest of the assembly must be completed, requiring even more joints and cuts to be made. Such a process involves a high level of skill on the part of the craftsman and requires substantial amounts of time to complete. A typical bathroom lavatory installation requires 10 to 12 sweat joints, 4 to 5 glue joints and 6 to 8 cuts.

[0004] In addition to the multiple component parts required for the finished plumbing assemblies, the plumbing assemblies are generally installed within the interior space of the walls of a building. Since the plumbing assemblies are contained substantially within the wall, these components must be installed before the wall is finished. In the case of installation where a concrete slab foundation is used, the plumber must install the initial components of the plumbing assembly before even the building frame of the structure is in place. In this situation, great care must be taken so that the initial components of the plumbing assemblies are in the correct orientation so that they will be completely enclosed within the finished wall. If the initial plumbing assemblies are not in the correct orientation, subsequent modification may be required to ensure the completed assemblies fit inside the wall as desired, adding additional time and cost to the construction process. Further complicating the issue the plumbing assemblies must be at the appropriate finished height for connection to the particular plumbing fixture.

[0005] The multiple component parts and methods of installation that are currently used make the installation process labor intensive and time consuming. In addition, since skilled craftsmen must be employed to produced the finished installation, the installation process is expensive. Finally, the installation process necessitates excessive waste and material cost, since a significant portion of material is lost as a result of cutting the components to size to produce a plumbing assembly of the correct dimensions.

[0006] Therefore, there is a need in the plumbing field for modular, prefabricated plumbing assemblies that are both economical and efficient to install so that the installation process can be accomplished in less time, at less cost with less waste.

[0032] finishing kit shall mean all components necessary to connect the plumbing assembly to the plumbing fixture to produce a finished installation, including, but not limited to, stops, trim pieces, supplies, traps and adapters; and

[0033] rough in dimensions shall mean the initial estimation of the measurements required to ensure the plumbing assembly is at a finished height and orientation to receive a plumbing fixture.

[0034] The present disclosure describes prefabricated, modular plumbing assemblies which are suitable for installation in a building. The plumbing assemblies of the present disclosure are prefabricated and modular, incorporating all the measurements and components required for a successful installation. The instant disclosure describes several modular plumbing assemblies for the following applications: 1) installation of sink, laundry sink or lavatory; 2) installation of water heater; 3) installation of washing machine; 4) installation of water closet; 5) installation of hose bibb; and 6) installation of bath, shower or bath/shower combination.

[0035] General Principles Applicable to All Plumbing Assemblies

[0036] Although the present disclosure describes several modular plumbing assemblies for specific applications, each of the modular assemblies rely on the same design and construction principles. Current plumbing installation methods require that multiple component pieces be cut, assembled and installed on the building site. This requires that: a) the plumbing assembly be assembled and installed with rough in dimensions on site so that the finished plumbing assembly is at the appropriate finished height and orientation; b) the pipes be cut on site, which produces wasted materials; c) the pipes be joined together on site; and (d) the proper component parts gathered together and brought to the site to avoid delays in installation. The design and construction principles of the modular plumbing assemblies of the present disclosure allow plumbing assemblies to be installed efficiently, cheaply and accurately. The plumbing assemblies are designed so that, in most cases, only 1 measurement must be made by the installer on site in order to ensure that the plumbing assembly is at the appropriate finished height for connection to a plumbing assembly. This greatly reduces the time required for installation and the accuracy of the finished installation. In addition, since the assemblies are modular and prefabricated, the problems of costly and time-consuming on site assembly and wasted material are avoided since there are fewer cuts to make and fewer joints to assemble. Additional features include mounting brackets and assembly instructions. The mounting brackets (described in more detail below) are designed to secure the pipes comprising the modular plumbing assembly to the building frame of the structure quickly and securely. The brackets, therefore, allow the components of the plumbing assemblies to be installed in the correct relationship to one another and at the appropriate finished height and orientation for connection to the plumbing fixture. The installation instructions allow the installer to quickly and accurately prepare the main plumbing system of a building to receive the modular plumbing assemblies and to install the modular plumbing assemblies of the present disclosure, so that the plumbing assemblies are in the appropriate orientation and finished height for a given installation.

[0037] Use of the modular plumbing assemblies of the present disclosure greatly simplifies the installation process, decreases the labor cost and installation time, saves on material costs and material waste and reduces the installation errors inherent in the current methods for installing plumbing assemblies. For example, while a typical bathroom lavatory installation requires 10 to 12 sweat joints, 4 to 5 glue joints and 6 to 8 cuts, using the modular plumbing assembly of the present disclosure to install a bathroom lavatory reduces the number of sweat joints to 4, the number of glue joints to 2 and the number of cuts to 4. In addition, the modular plumbing assembly places the plumbing in the appropriate orientation and at the correct finished height to receive the lavatory fixture, thereby eliminating almost all installation errors.

[0038] The modular plumbing assemblies can be sold as complete units in kit form, or can be sold as individual pieces. Each kit would contain the appropriate modular plumbing assembly for installation to a specific plumbing fixture and installation instructions sufficient to permit one of ordinary skill in the art in the plumbing field to complete the installation. Optionally, the kits may also include a finishing kit that includes all the trim pieces, stops, adapters and supplies needed for a particular installation. The finishing kit provides the advantage that all the components for a professionally finished installation are present and that these components are matched to fit the diameter pipes used in a particular installation. This eliminates the need to purchase the components separately and ensures a pleasing finished look to the installation. The content of the finishing kit will vary depending on the particular plumbing assembly to be installed. In addition, the plumbing assemblies may be supplied as one unit, or each assembly may be broken down into smaller assemblies. In general it will be necessary to provide smaller assemblies when installation of the plumbing assemblies occurs on a concrete slab foundation.

[0039] In the descriptions that follow, the modular plumbing assemblies will be described as incorporating polyvinylchloride (PVC) pipe for the drain pipes and copper pipes for the water supply pipes, extensions and other water carrying pipes. It is understood within the field that PVC covers all schedules and thicknesses of PVC. However, it should be understood that any material that meets local building codes can be substituted for PVC and/or copper, and still be within the spirit of the disclosure. For example, chlorinated polyvinylchloride (CPVC), poly-butylene, butylene or stainless steel can be used in place of copper and cast iron or copper can be used in place of PVC, when local building codes permit. In addition, detailed description of pipe diameters is not given, and is not critical to the present disclosure. The proper pipe diameter for a particular application is well within the knowledge of one of ordinary skill in the art in the plumbing field, and the present disclosure should be understood to include all relevant pipe diameters. Furthermore, when caps or sealed ends are incorporated into a modular plumbing assembly, the caps and sealed ends may be color coded with red or blue caps or markings, with the red color indicating a hot water connection and the blue color indicating a cold water connection. In addition, although the plumbing assemblies are described as being connected to the main plumbing system of a building, it is understood that the components of the main plumbing system may vary depending on the plumbing assembly installed. Finally, when two pipe ends are joined together to form joints, it is preferred that in order to facilitate joint formation, one of the pipe ends will contain a standard bell connection, and the other of the two pipe ends will be adapted to connect with the bell connection. Alternatively, if bell connections are not employed, a suitable coupling can be used to join the two pipe ends together, with the coupling being essentially a short section of pipe with two bell ends.

[0040] The following examples illustrate preferred embodiments of the modular plumbing assemblies and alterations, such as, but not limited to, the pipe materials, assembly steps, joint connections and other variables within the knowledge of one of ordinary skill in the plumbing field should be considered within the scope of the present disclosure.

[0041] Modular Plumbing Assembly for a Lavatory Sink or Laundry Sink

[0042] A modular plumbing assembly, 10, for a lavatory, sink or laundry sink is described below and shown in FIGS. 1 and 2. FIG. 1 illustrates an embodiment of the assembly 10 for installation on a concrete slab foundation where the assembly 10 is composed of a primary assembly 12 and a secondary assembly 14. It should be considered within the scope of the disclosure to provide assembly 10, and the other assemblies described hereafter, as a single unit, further eliminating the time and manpower required to install the assemblies.

[0043] In its most basic form, assembly 10 comprises 2 water supply pipes and a drain pipe. Throughout the remainder of the specification and the claims that follow the water supply pipes may be designated as hot and cold, or simply referred to without a designation of hot and cold it being understood that one water supply pipe will supply hot water and the other water supply pipe will supply cold water. The assembly 10 comprises a primary assembly 12 and a secondary assembly 14. The primary assembly 12 further comprises a bracket 70, hot and cold water supply pipes 20A and 20B and a drain pipe 28. The hot and cold water supply pipes 20A and 20B each have an upper end 22A and 22B and a lower ends 24A and 24B. Supply pipes 20A and 20B may be covered by color coded caps 25A (red) and 25B (blue) to prevent debris from entering the pipe during installation and to identify the pipes quickly during installation. Supply pipes 20A and 20B each have bell connectors 26A and 26B on lower end 24A and 24B. The drain pipe 28 has a sealed upper end 30 and a lower end 32, with a bell connector 34 on lower end 32, and at least one cut line 31 on sealed upper end 30. The sealed upper end 30 functions to provide a seal so that the drain pipe assembly can be pressure tested before further installation continues.

[0044] The secondary assembly 14 further comprises hot and cold water supply extensions 50A and 50B, sealed fixture extensions 58A (red end) and 58B (blue end), a drain pipe extension 60, a drain connection 68 and a mounting bracket 70. The water supply extensions 50A and 50B each have upper ends 52A and 52B and lower ends 54A and 54B, with bell connection 55A and 55B on lower ends 54A and 54B and air chambers 56A and 56B on upper ends 52A and 52B. The fixture extensions 58A and 58B have at least one cut line 59A and 59B on the sealed ends and extend laterally from the hot and cold water supply extensions 50A and 50B at predetermined locations so that they will be at the appropriate height for connection to the plumbing fixture. The drain pipe extension 60 has an upper end 62 and a lower end 64, with bell connections 66A and 66B on upper end 62 and lower end 64, respectively. A sealed drain connection 68 is located on drain extension 60 and extends laterally from the drain pipe extension 60. The lengths of the fixture extensions 58A and 58B and the drain connection 68 are such that they extend laterally a sufficient distance to extend beyond the finished wall for connection to the plumbing fixture. FIG. 2 further illustrates the configuration of the fixture extension 58A and the drain connection 68. (fixture extension 58B is obscured by fixture extension 58A). The diameter of the drain connection 68 is selected so that it is the proper diameter for the particular plumbing fixture being installed. For instance, if a bathroom lavatory is being installed, the drain connection 68 will have a diameter of approximately 1¼ inches. If a laundry tub/sink is being installed, the drain connection 68 will have a diameter of approximately 2 inches. The incorporation of the proper size drain connection 68 eliminates the need to reduce or enlarge the diameter of the drain connection with bulky adapters. The result is a finished installation that is sure to be enclosed withing the finished wall and that is aesthetically pleasing to the eye since openings in the finished wall are correct diameter and the trim pieces will fully cover the openings in the finished wall. The components of the primary assembly 12 and the secondary assembly 14 are secured in brackets 70 to building frame members 16.

[0045] The bracket 70 (shown in FIGS. 3A and 3B) may be constructed from any type of material that will provide a rigid structure, such as stamped galvanized iron. The dimensions of the bracket 70 can be varied, but in a preferred embodiment the bracket 70 is 3½ inches wide and 14½ inches in length in order to conform to the width and the spacing of the frame members 16 in a typical building. The bracket 70 comprises a base 72 having two outer sides 74A and 74B and right and left ends 76A and 76B, respectively. Downwardly turning legs 78A and 78B extends from each of the ends 76A and 76B, forming generally a 90 angle with the base 72. Gang nails 80A and 80B are incorporated into the legs 78A and 78B to secure bracket 70 to frame members 16. Other means to secure the bracket 70 to the frame members 16 include, but are not limited to nails, screws or bolts. Fins 82A and 82B may optionally be attached to each leg 78A and 78B to receive the frame members 16. In a preferred embodiment, the fins 82A and 82B extend at a 90 angle from each leg 78A and 78B, forming a channel 84 to receive the frame member 16. The base 72 contains a plurality of openings 86 to receive the components of assembly 10. The openings 86 are generally circular, with a diameter adapted to securely receive the components of the plumbing assembly. The openings 86 may optionally contain sleeves 88. The configuration of openings 86 on base 72 will vary depending on the particular installation and alterations in the configuration should be considered within the scope of the present disclosure. In the embodiment shown in FIG. 3B, bracket 70 is adapted to receive the components of the primary assembly 12 and one opening 86 is centered on base 72 and two openings 86 are offset from the center of base 72 by 4 and 8 inches to correspond to standard installations.

[0046] The installation of assembly 10 will vary depending on the circumstances of the installation as stated in the installation instructions provided with assembly 10, but will follow the principles described below, with differences from these general principles being apparent to one of ordinary skill in the art in the plumbing field. As described above, for concrete slab foundations it is necessary to install the modular plumbing assembly 10 in two steps. The first step is the joining of the primary assembly 12 to the main drain pipe 90. The height of drain pipe 90 from the finished floor will vary depending on the plumbing fixture to be installed, with the proper height being given in the installation instructions. Main drain pipe 90 is cut so that it extends the appropriate height from the finished floor. This is the only measurement required in the installation of assembly 10.

[0047] The remainder of the measurements are predetermined through the structure of the primary assembly 12 and the secondary assembly 14 and use of bracket 70, so that the completed plumbing assembly 10 will be at the appropriate finished height and orientation for the plumbing fixture to be installed.

[0048] Once the main drain pipe 90 is cut to the proper height, the primary assembly 12 is secured to the main drain pipe 90 via a glue joint between the bell connection 34 on the lower end 32 of drain pipe 28 and the main drain pipe 90. Once the drain pipe 28 is connected to the main drain pipe 90, the main water supply lines 92A and 92B may be connected to hot and cold water supply pipes 20A and 20B via a sweat joint between bell connection 26A and 26B on lower ends 24A and 24B and the main water supply lines 92A and 92B. The primary assembly 12 is secured to the frame members 16 by the gang nails 80A and 80B on bracket 70.

[0049] Next, the secondary assembly 14 is secured to the primary assembly 12. Since the primary assembly 12 and the secondary assembly 14 are a constant length for all plumbing assemblies 10, the length of the main drain pipe 90 will determine the finished height of the modular plumbing assembly 10. The drain pipe 28 is cut along cut line 31 for attachment to the drain extension 60. Although the order of connection can be varied, it is generally more efficient to connect the drain pipe extension 60 to the drain pipe 28 via a glue joint between the bell connection 68 of drain extension 60 and the upper end 30 of drain pipe 28. The water supply extensions 50A and 50B are then connected to the water supply pipes 20A and 20B via a sweat joint between bell connections 55A and 55B on water supply extensions 50A and 50B and the upper ends 22A and 22B on hot and cold water supply lines 20A and 20B. The water supply extensions 50A and 50B can be moved up and down relative to bracket 70 if needed in joining the water supply extensions 50A and 50B to the water supply pipes 20A and 20B. The bracket 70 is then secured to the frame members 16 via gang nails 80A and 80B. At this point installation of the modular plumbing assembly 10 is complete, and the finished walls of the structure can be installed to cover the modular plumbing assembly 10, with only extensions 58A and 58B and drain connection 68 extending through the finished wall. The finished modular plumbing assembly 10 is at the appropriate finished height and orientation for connection to the selected plumbing fixture. A shown in FIG. 2, the extensions 58A and 58B are sealed for pressure testing, and it is necessary to cut the ends of extensions 58A and 58B along the pre-marked cut lines 59A and 59B before hook-up to the specific plumbing fixture. The sealed end of drain connection 68 must also be cut before hook up to the plumbing fixture. The optional finishing kit contains the stops, supplies, traps and adapters required for connection of the extensions 58A and 58B and drain connection 68 to the plumbing fixture. If installation of assembly 10 occurs after the frame members 16 are installed, as in a building with an off-grade floor system, primary assembly 12 and secondary assembly 14 may be supplied as one unit and secured to frame members 16, with installation to the main drain pipe 90 and the main water supply lines 92A and 92B being essentially as described above.

[0050] Modular Plumbing System for Water Heater Installation

[0051] A modular water heater plumbing assembly, 100, is described below and shown in FIGS. 4-6. FIG. 4 illustrates an embodiment of assembly 100 which is composed of a primary assembly 102, a secondary assembly 104 and optionally, a tertiary assembly 106 (shown in FIG. 6). It should be considered within the scope of the disclosure to supply all of these assemblies, or a combination thereof, as one unit. The primary assembly 102 further comprises hot and cold water supply pipes 108A and 108B, respectively, a relief pipe 116 and a bracket 70. The bracket 70 is essentially the same as previously described except that openings 86 may be of different diameter and configuration in order to securely receive the components of assembly 100. The hot and cold water supply pipes 108A and 108B each comprise lower ends 110A and 110B, upper ends 112A and 112B and bell connections 114A and 114B on lower ends 110A and 110B. The relief pipe 116 comprises a lower end 118, an upper end 120 and a bell connection 122 on lower end 118. In addition, color coded caps 115A (red), 115B (blue) and 115C (green) are supplied for the hot and cold water supply pipes 108A and 108B and the relief pipe 116, respectively, to keep debris from entering the pipes during installation and to quickly identify the pipe during installation.

[0052] As illustrated in FIGS. 4, 5A and 5B, the secondary assembly 104 further comprises sealed hot and cold water supply extensions 124A and 124B, a sealed relief pipe extension 134 and a bracket 70. The sealed ends 128A and 128B of the hot and cold water supply extensions 124A and 124B may be marked with a cut line 129A and 129B and coded with a red and blue color respectively. Likewise, the sealed end 138 of relief pipe extension 134 may be marked with a cut line 139 and coded with a green color. The hot and cold water supply extensions 124A and 124B have lower ends 126A and 126B, upper ends 128A and 128B, with bell connections 130A and 130B on lower ends 126A and 126B and air chambers 149A and 149B. The relief pipe extension 134 has a lower end 136, an upper end 138 and a bell connection 140 on lower end 136. The components of the primary assembly 102 and the secondary assembly 104 are secured in brackets 70. The upper ends 128A, 128B and 138 extend laterally from the plane defined by the lower ends 126A, 126B and 136 and are a sufficient length to extend through the finished wall to allow connection to the water heater.

[0053] As illustrated in FIGS. 6A and 6B, the tertiary assembly 106 comprises hot water connection 142, a relief connection 144 and a cold water connection 146. The hot water connection 142, relief connection 144 and cold water connection 146 are provided as pre-assembled units. The hot water connection 142 has a first end 170, a second end 172, a bell connection 174 on the first end 170 and a dielectric union 160 on its second end 172. The relief connection 144 has a first end 180, a second end 182, a bell connection 184 on the first end 180 and a dielectric union 160 on its second end 182. The cold water connection 146 has a first end 150 and a second end 152, with a bell connection 154 on the first end 150, a valve 156 integral with cold water connection 146 and a dielectric union 160 on its second end 152. In a preferred embodiment, valve 156 is a gate valve, but other types of valves that allow for maximum water flow could also be used. The cold water connection 146 and hot water connection 142 are connected to water heater 194 through dielectric unions 160.

[0054] In contrast to the installation of modular plumbing assembly 10, modular water heater plumbing assembly 100 is generally installed after the building has been roughed in with frame members 16. Therefore, the assembly 100 may be installed as a single unit in both concrete slab and off-grade floor system constructions, or can be installed in smaller assemblies as described below. The final installation height of water heaters varies depending on the make and capacity of the water heater. The installer consults the installation instructions provided with the assembly 100 and determines the make and capacity of the water heater to be installed. The installation instructions provide the installer with the proper height for the installation of mounting bracket 70 containing the primary assembly 102. This is the only measurement required in the installation process for assembly 100. Since the length of the remainder of assembly 100 and its components is constant, the height of mounting bracket 70 determines the finished height of assembly 100.

[0055] Once the mounting bracket 70 is installed, the hot and cold water supply pipes 108A and 108B are connected to main hot and cold water supply pipes 190A and 190B, respectively, via sweat joints between bell connections 114A and 114B of hot and cold water supply pipe 108A and 108B and the main hot and cold water supply pipes 190A and 190B. The relief pipe 116 is connected to the main relief pipe 192 via a sweat joint between bell connection 122 on lower end 118 of relief pipe 116 and the main relief pipe 192. The primary assembly 102 is then ready to receive the secondary assembly 104.

[0056] The hot and cold water supply extensions 124A and 124B are connected to hot and cold water supply pipes 108A and 108B via sweat joints between the bell connections 130A and 130B of hot and cold water extensions 124A and 124B and the upper ends 112A and 112B of hot and cold water extensions 108A and 108B, respectively. The relief pipe extension 134 is connected to relief pipe 116 via a sweat join between bell connection 140 on lower end 136 of relief pipe extension 134 and the upper end 120 of relief pipe 116. The secondary assembly is then secured to frame members 16 via gang nails 80A and 80B on bracket 70, or other means as described above. Once the secondary assembly 104 is connected, the partially completed assembly is at the appropriate finished height for connection to the particular water heater selected for installation. At this point the finished walls of the building can be installed to cover the modular plumbing assembly 100, with only the upper ends 128A, 128B and 138 extending through the finished wall. The upper ends 128A, 128B and 138 are cut along the cut lines 129A, 129B and 139, respectively. The modular plumbing assembly 100 is now ready to receive tertiary assembly 106, if used. Since the modular water heater assembly 100 is installed after the structure has been roughed in with frame members 16, primary assembly 102 and secondary assembly 104 could be combined into one assembly if desired, and installed in one step.

[0057] The optional tertiary assembly 106 connects the assembly 100 to the water heater 194. The tertiary assembly 106 is designed to accommodate a finished wall dimension of ½ to 1 inch and allow for a clearance of 1½ to 2 inches from the finished wall. The hot water connection 142 is connected to the hot water extension 124A via sweat joint between bell connection 174 on first end 170 and the upper end 128A of hot water supply extension 124A. The relief connection 144 is connected to the relief pipe extension 134 via a sweat joint between the bell connection 184 on first end 180 and the upper end 138 of relief pipe extension 134. The cold water connection 146 is connected to the cold water supply extension 124B via a sweat joint between bell connection 154 on first end 150 and the upper end 128B of cold water supply extension 124B. The hot water connection 142, the relief pipe connection 144 and the cold water connection 146 are connected to the water heater 194 via male threaded connections on dielectric unions 160 and female threaded connections (not shown) on water heater 194 according to the water heater manufacturer's instructions and local building regulations. In the event the water heater 194 is not provided with female threaded connections, commercially available threaded adapters can be used to supply the appropriate threaded connection.

[0058] Because no sweat joints are required to connect the hot water connection 142, the relief pipe connection 144 and the cold water connection 146 to water heater 194, no heat is applied to the top of the water heater 194. A common result of applying heat to the top of the water heater 194 is damage to the components of the water heater, especially the cold water carrying pipe (not shown), which is often constructed of plastic. In addition, the threaded connection allows the water heater to be easily disconnected and replaced if required without extensive modification to the plumbing system.

[0059] Optionally, a finishing kit that contains the trim pieces, adapters and other components needed for a finished installation may be supplied with assembly 100. In the case of assembly 100, the finishing kit would include Teflon tape to be used in conjunction with the mechanical threaded connections.
